驱蚊香草组织培养与快速繁殖研究

以驱蚊香草不同部位为外植体，进行离体快繁试验，结果表明：外植体以叶片和顶芽容易诱导产生愈伤组织，最高诱导率达90％；诱导培养基以Ms＋6-BAl．0～2．0mg／L＋NAA0．2mg／L效果较好，平均芽诱导分化率达85．6％-86．7％；增殖培养基以MS＋6-BA1．0mg／L＋NAA0．1mg／L效果最好，丛生芽增殖最多，繁殖系数达6．12倍；诱导生根培养基以1／2MS＋NAA0．3mg／L最佳，生根率达到100％；假植20d后，移栽成活率达100％。

Tissue Culture and Rapid Propagation of Cymbopogon citrates

The various parts of Cymbopogon citrates were chosen as explants to carry out rapid propagation in vitro.The result demonstrated that: the lamina and terminal bud were propitious to callus induction,the maximum rate of inducement could reach 90%;the preferable induction culture medium was MS 6-BA 1.0~2.0 mg/L NAA 0.2 mg/L with the average bud inducement differentiation rate of 85.6%~86.7%;the best proliferation culture medium was MS 6-BA 1.0 mg/L NAA 0.1 mg/ L with the most number of clustering buds,and the reproduction quotiety was 6.12 times;using 1/2MS NAA 0.3 mg/L as rooting inducement culture medium,the rooting rate could reach to 100%;the survival ratio of the transplanted seedlings reached 100% after 20 days'temporary planting.
